Abstract: Touch input devices are provided with the capability of sensing a capacitive load in a two-dimensional array while also being able to sense deflection or movement of the input device in multiple different locations under an input pad. A touch input device can beneficially be used in a remote control device and can be used with multiple input buttons or platforms overlaying multiple capacitive touch input regions on a capacitive touch sensor substrate. Movement and position of a capacitive load can be tracked and calculated via output signals from a set of electrodes or other capacitance sensors with irregular shapes, with inconsistent distances from the capacitive load, and which are positioned below variable materials and material compositions. Thus, tracking gestures and taps can be detected using the capacitance sensing devices, and deflection input can be detected using switches or other actuators situated under the capacitance sensing devices.

Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

Abstract: A wireless power system includes an electrically-balanced inductor in a transmitter device and an electrically-balanced inductor in a receiver device. The electrically-balanced inductors can be formed by introducing crossovers between radially-adjacent portions of two separate turns of each inductor. The crossovers balance the electric field generated by the transmitter device when transferring power to the receiver device.
